leishmaniasis is a common parasitic disease in tropical and subtropical areas of the world. police personnel deployed in the suburbs and rural areas are the most often exposed to the potential risk of cutaneous leishmaniasis. furthermore, since the same police personnel are sent on duty to other places, their migrations can also play a considerable role in the transmission of this disease to th...

introduction : adverse health effects of exposure to environmental tobacco smoke (ets) among non-smokers have been studied occasionally in developing countries. the aim of this study was to determine the effects of exposure to ets on outcome in pregnancy methods: in this descriptive and analytical study 600 non-smoking women delivering a singleton live baby were studied in delivery room in haja...

objectives: specific language impaired children, despite being normal in cognitive and neurological characteristics, and also normal levels of hearing, experience multiple problems in syntax comprehension. this study compared the passive comprehension as one of syntactic structures in persian-speaking typically developing children and specific language impaired children. methods: 10 children wi...

To approach this goal, we develop a detailed 1D model to describe the DMFC on the electrode and cell level, based on the in-house modeling framework DENIS. A two-phase flow model is implemented for the transport in gas diffusion layer (GDL) and catalyst layer (CL) at the anode side, whereas we consider only the gas phase at the cathode side. Electrochemistry is described by multistep mechanisms...

For the last decade, dimethyl ether (DME) has been considered a promising alternative fuel for direct fuel cells because of several advantages over methanol. In this work, PtRu catalysts with a wide range of Pt-to-Ru ratios were screened for the direct DME fuel cell (DDMEFC) performance for the first time. Overall, Pt50Ru50 performs best in the high and middle voltage ranges, whereas Pt80Ru20 p...

introduction: the passive sentence structure is one of the most interesting syntactic structures on language development. studies in some languages have indicated that comprehension of this syntactic structure takes place late in the language acquisition process. therefore, the purpose of this study is to investigate the comprehension of active and passive structures in 48-59- and 60-71-month-o...
